Try the code below:

    var int2ByteArray = function(i, minByteCount) {
        var result = [],
            buf = code = +i,
            offsetCount = 0;
        while ((buf = code>>(8 * offsetCount)) || offsetCount < minByteCount) {
            buf = buf & 0xFF;
            ++offsetCount;
            result.push(buf);
        }
        return result.reverse();
    };

    var ascii2ByteArray = function(s) {

        if (!s) return 0;
        var result = [];
        [].map.call(s, function(c) {
            result = result.concat(int2ByteArray((typeof(c)).toLowerCase() == "number" ? c : c.charCodeAt(0)));
        });
        return result;
    };

    // You got the blob here, do whatever you want.
    var blob = new Blob(new Uint8Array(ascii2ByteArray(jsonse)), {type:"text/json"});

The matrix is to convert a string(stringfied by JSON.stringify) in to a Uint8Array that could be used making a blob. I happened make something like that before, hope it's useful.
